Little is known of the biology and ecology of Lasiopetalum sp. Mount Caroline (S.D.Hopper SDH 6381); however, juvenile plants of another species of Lasiopetalumproduced viable seeds two years after a fire (WA DEC 2007). This species may be an obligate re-seeder similar to other species of Lasiopetalum(Clarke 2006) whereby it is killed by fire and germinates following disturbance (Wilkins et al. 2007). Layering has been observed in a mature plant of another species where roots are produced from lateral above-ground branches that touch the soil. This could be a survival strategy in the absence of fire (Wilkins et al. 2007).

Future population due to such low numbers of plants Insect predation on seeds Subpopulation 1 extreme Insect predation of seed is currently the major threat to Past and present the nearby Tetratheca deltoidea population Decline in habitat condition whole population extreme Granite soils are shallow and susceptible to drying Future through climate change which is exacerbated by the drying climate.
Climate change modelling for the south west region predicts a decline in rainfall; and some seasonal shift to summer rainfall events; which is likely to increase the potential impact of drought on the species.
